How can I change the Delta Sigma ADC Buffer mode configuration during run time? I have different kind of sensors:

0-5V with the ADC buffer in "Bypass Buffer" mode

+/-15mv with the ADC buffer in "Level Shift" mode

The ADC_SelectConfiguration() should change the ADC configuration but not the buffer options.  I also added a delay to let the change take place before to start the conversion (CyDelayUs(50);)

Is there anything I should add to select different configuration for my buffer?

Thank you and have a great day

Hi

I encountered a problem while using AMUX to switch channel for 16 bit or higher resolution Delsig ADC.

I verify that in CY8CKIT-050 board and run the  example project as below show,  it can works as expected.

but when I change the ADC resolution to 16 bit, and input fixed voltage like half of power, the readout  is  abnormal of which jitter is serious,  I think the Amux cause that, so I increase the delay time before start ADC to keep enough time after change channel, no matter what long I delay, the problem is still exist. I am confused about this problem.

I hope someone can help me solve this problem,  thanks very much!

I got the USBUART example working, but all that does is show up as a COM port and echo characters back to the computer.  Is there a bridge example, so it shows up as a COM port, but passes the characters through to a hardware UART component, out of a hardware pin, and vice versa?

Hi All,

I am trying to interface PSOC 5LP Prototyping Kit, with a 16x2 LCD (RG1602A) over Port P12 [6:0] and have made the corrections properly ( triple checked).

And made the DWR and pin assignment as well as Step 8 (main.c) as mentioned in: http://www.airsupplylab.com/psoc5-lp/17-psoc5-lesson-07-interfacing-character-lcd-display-module-with-psoc.html#for-cypress-cy8ckit-059-prototyping-kit

I have connected the LCD pins according to above article on P12[6:0] and programmed the PSOC.

But there are no characters displayed on the LCD, instead the first row is all black boxes as shown in the image below:

And i have searched and found out the following info from one of microchip forum: "One row of boxes at the top of a two line display almost always indicates either bad initialisation or a data or control wiring fault and is because the diisplay controller is still in its power up default of single line mode which needs a different contrast voltage to two line mode.

As the display section of the schematic looks sane, the problem is probably either the actual sequence used or its timing - either inter-command delays or setup and hold timing for strobing out each nibble."

Can you please help on what to do in this scenario and  what could be the issue and how to resolve it?

Hi,

is there a way to clear the notice list in psoc creator.

And it would be top, if the list could be cleared at each compilation.

I am trying to get som random numbers from the PRS hardware.

But I get the same number every time.

How du I get different numbers ?

Ran1=PRS_Read();
Ran2=PRS_Read();
Ran3=PRS_Read();
Ran4=PRS_Read();
Ran5=PRS_Read()*256;

There is no PRS_Step() finction in Psoc_creator 4.4 as I can see.

Regards Erik
